Group F7 Swing Frequency, Fixed Length and Counting
The swing frequency function is applicable to textile and chemical fiber
industries and applications where traversing and winding functions are
required.
Swing frequency means that the inverter output frequency swings up and
down with the setup frequency (frequency command is selected in F0-01) as
the center, and the trace of running frequency at the time axis is as shown in
Fig.6-22.The swing amplitude is set in F7-00 and F7-01.
When F7-01 is set to 0, meaning the swing amplitude is 0, or F7-03 is set to 0,
the swing frequency will have no function.

It is used to determine the amplitude value.
0: Relative to the center frequency (F0-03 frequency source selection): It is a
variable swing amplitude system, with the swing amplitude changing with the
center frequency (setup frequency).
1: Relative to the maximum frequency (F0-04 maximum output frequency): It
is a fixed swing amplitude system, with fixed swing amplitude that is
calculated by the maximum frequency.
